Revenue

The decreases were driven by a shift in service offering mix, as we continue to experience a reduction in Video and Telephony RGUs. These decreases were offset by increases in average revenue per unit (“ARPU”), as HSD customers continue to purchase higher speed tiers; coupled with HSD and Video rate increases issued in 2021 and an increase in volume attributable exclusively to the addition of HSD subscribers.

These decreases were primarily due to decreases in data center revenue.
Other Revenue from continuing operations totaled $7.8 million and $31.4 million for the quarter and year ended December 31, 2021, down $2.3 million and $3.3 million compared to the corresponding periods in 2020, primarily due to decreases in advertising, service call fee, and line assurance revenue.

The decrease for the quarter-to-date period is primarily related to a decrease in marketing expenses. The increase for the year-to-date period is primarily attributable to increases in marketing, compensation (including stock compensation), professional service and legal expenses associated with the sale of five of our markets and the refinancing of our long-term debt, partially offset by decreases in costs associated with digital transformation initiatives.
